Check your VGA cables to make sure it's properly connected (if you haven't already). If that does not work, Take the CMOS battery out of your motherboard and leave it out for a minute, then put it back in. If that still doesn't work, make another post with more specific information about your system.

Have a t 3256 emachine. Hard drive will not boot. Fans run. No lights coming on. My acer s200hl led monitor says no signal. Help with issue.

Typically pressing F2 will enter the computer BIOS. Try striking the F2 key repeatedly just as you turn on power. If you are not able to access the BIOS screen then it is likely a power supply failure.

If you are able to access the BIOS con firm that the BIOS has found the HDD and reports on the drive. The format is different for every machine. It is either an IDE or SATA. The DHH that contains the boot sector and OS (operating system-windows) needs to be confirmed to be present in the BIOS for the computer to boot. The computer should still continue but issue an error message that no boot was found.

The fact that no beeps or lights come on and if BIOS is not accessible it would be power supply or motherboard. Remove plug from wall and allow to set at least a minute. Try rebooting.


26057080-gnp32lebnhderv5f2k4gkrdu-5-2.jpg If you are not able to reboot then you can assume that all of your files and documents are still safe. The concern is without technical experience going into troubleshooting the power supply or motherboard can put either your HDD or yourself in harms way. If you have a friendly computer repair suggest you get an estimate first of troubleshooting cost and have them determine the problem. If motherboard make sure that a replacement computer will take your HDD. It would not be installed as a OS boot drive but as a drive where yo could copy over all of your photos and documents into a new PC.

Hope this has helped?

My transcend external hdd power unit is 5vdc .it has two usb one for power .i hv adapter that converts ac to 5vdc which is charger of my tablet.can i use it to power up hdd externally and connect another...

Without seeing the specs of the adapter it's hard to tell the voltage is correct but what you need to be concerned about is the amperage(mA) USB ports on computers only put out a max of 500mA per port the tablet charger could put out more than that.

After i Read your Explaination,i really sure if the Problem is at your Computer POWER SUPPLY.
Change your Power Supply to Higher Watt.
i Recomended to you to Using SIMBADA Power Supply ATX.
and to Fix your HDD bad Sector,Try to use LLF (Low Level Format).
LLF will destroy all data and Partition.So after you Format using LLF,you need to make a New partition at your HDD.
LLF is Working for me to Fix Bad Sector in a So many times.

Hello Sir, hi, the wires on your casing are usually labeled, like in the picture below: cyberdyers_0.jpg

the power led green wire goes to the power led + and the white goes to the - . Now the HDD + goes to the HDD + the red wire, power switch can be interchange, same as the reset switch.

What is the red /white wire for that comes out the back ,marked H.H.D Led ? where does it go

actually the HDD led was nothing all about.. it will just support the hard disk to have power.. if you have a good power supply and you trust your power supply .. the hdd led is no use..

Computer was working when the power turn off and power led turns red

IT seems that the power destroy your power supply, the question now when you try to turn your computer, do you hear anything? or it doesnot turn on at all. if this is the case, replace the power supply.

Thanks for using Fixya

3 red lights and yellow power supply light

at the very least the main board is acting flaky with the 3 red lights flashing. Here is tutorial courtesy of LLAMA to show how to resolve that problem:

As far as the yellow light on the power supply is concerned. Unhook it from the Xbox 360 and only plug it into a power outlet. If the light is yellow then the power supply is bad. If the light stays green then plug it into the xbox 360, if it tells yellow then, at that point you know that the main board is causing the yellow light on the power supply and that means the main board is bad.

the power supply is probably bad. It's really hard to tell without a little more information. When my power supply went bad on my computer. the hdd light would come on but nothing else and the computer would not even try to start.the power supply puts out several different voltages with both positive and negative outputs.

When powering up my computer, I get a failure. Primary hard drive 1 not found Strike the F1 to continue F2 to run the set up utility. I think the power supply fan is not working. What do I do?

your system can not detect your primary hard disk which host the operating systems,so you check the data cable to the hard drive and the power supply to the hard drive for supply
